Add-in deployment problem

Hi,

I made an Outlook add-in. I created setup files and deployed it to another computer. I login as USER1 and installed add-in and used CASPOL to set permission to the user to run. It worked well.

I then log out and log in as USER2. Open the Outlook, it didn't work. I then used CASPOL to assign permission to USER2 to run the add-in. It still didn't work.

My question is: how can I install add-in once and set the security in one go, then every user on this computer can use my add-in? Should I do anything on setup project?

Thanks,

Danny Huang
